@Wizz Where would you put them? He doesn't need to go for the cities, just visit graveyards and such. Can you imagine how many somewhat fresh corpses there still are after the War of Five Kings? 
Well, like we saw in the battle between Danaerys and the Lannister forces, the ballista was mounted on a wagon, meaning they could be mobile. It might be a bit of a desperation move, but with stakes that high it'd probably make sense to send forces with ballistae to the biggest battlegrounds, or keep a few patrolling to catch him between points A and B, at least forcing him to stay on the move. All the Night King might gain is a few isolated pockets of undead at a time without White Walkers to guide them or raise more, and it would only take one dragonglass missile scoring a hit anywhere to snuff out the dragon. Seems like the risk he would be taking vs. just staying with his massive ever-growing horde and the other Walkers would be pretty extreme.
ETA: I mean the dragon is enormous and he could probably take other Walkers with him and drop them off at key points and then each Walker could potentially grow their pockets of undead until eventually they all merge back up and Westeros is proper fucked, but then you've only got one target in each swarm that you need to eliminate given that we've seen the wights collapse after the Walker that animated them is destroyed.
It's not a terrible idea at all @Arkandel and I think if the scenario were to "really" play out rather than be written to be as dramatic and entertaining as possible it'd be something the Night King would be foolish not to consider, but IMHO swarm tactics just seem to make more sense for the undead than guerilla warfare given their weaknesses.
